Superfluid Turbulence : Numerical simulations on supercomputers

Spectra of velocity in superfluid turbulence with evindence of bottlenecking at low temperature in DNS simulation of the two-fluid model truncated at a scale corresponding to the inter-vortex spacing. (see EPL 2011)

This work is done in collaboration with Emmanuel Leveque from the ENS Lyon. Our first steps in this field were initiated thanks to an original idea of Carlo Barenghi from the University of Newcastle, UK (see our EPL 87:54006 [2009] ).
